Description of our inter-related QUERI supported projects

Project	Type	Participants	Goals
TIDES	Action research partnership with formative evaluation	◆ Primary care, mental health, nursing and administrative leaders from three regional veterans health networks; ◆ Experienced depression care researchers; and ◆ Depressed veterans.	Study feasibility and safety of evidenced-based quality improvement for depression care. Steps included: 1) Adapt depression collaborative care models to VA settings through Evidence-Based Quality Improvement for Depression (EBQID); 2) Support and evaluate depression collaborative care implementation; and 3) Prepare for dissemination of depression improvement methods and materials throughout the VHA.
WAVES	Site-randomized controlled trial	◆ TIDES sites and matched control sites, and ◆ Veterans enrolled in primary care clinics screened for depression.	Implement & test depression collaborative care using TIDES evidence-based model.
COVES	Mixed method; administrative data analysis and qualitative interviews	◆ Stakeholders (patients, clinicians, administrators), and ◆ Administrators of databases of veterans' records.	Understand cost and value tradeoffs of TIDES implementation using VA cost information and semi-structured interviews with TIDES stakeholders.
ReTIDES	Regional demonstration project with program evaluation	All levels of VHA administrative structure including: ◆ Central Office, ◆ 4 regional health networks and administrative control networks, ◆ VA medical centers, ◆ Clinics, ◆ Providers, ◆ Administrators, and ◆ Patients.	Support progress of TIDES collaborative care model toward national VHA implementation. Sustain and spread TIDES evidence-based depression care model to additional VHA sites
